Research by one economist suggests that lead poisoning may cause a person to engage in criminal activities, which counties with high lead levels having higher murder rates.
"The theory offered by the economist, Rick Nevin, is that lead poisoning accounts for much of the variation in violent crime in the United States. It offers a unifying new neurochemical explanation for fluctuations in the crime rate and is based on studies linking exposure to lead in children with violent behavior later in their lives.
What makes Nevin's work persuasive is that he has shown an identical, decades-long association between lead poisoning and crime rates in nine countries.
...
Through much of the 20th century, lead in U.S. paint and gasoline fumes poisoned toddlers as they put contaminated hands in their mouths. The consequences on crime, Nevin found, occurred when poisoning victims became adolescents. Nevin does not say lead is the only factor behind crime, but he says it is the biggest factor."
